-
摘要: 证明带有自由面的轴对称液体圆射流和环状射流的控制方程在有势运动的情况下具有Hamilton结构, 其Hamilton函数为射流的总能量, 并给出正则变量的表达式.Abstract: It is shown that the governing equations describing thepotential motion of axisymmetrical liquid jets have a Hamiltonian structure.Round and annular jets are discussed. The Hamiltonian is the total energy ofthe jet, and the expressions for the canonical variables are given.
